The Crusades were designed to “cleanse” the Holy Land of its Muslim leaders, but the hatred of the Jews motivated the Crusaders to slaughter Jews along the way.
The first Crusade began from Rouen, France in 1096. It was reported that the Crusaders of Rouen said:
“We desire to combat the enemies of God in the East; but we have under our eyes the Jews, a race more inimical to God than all the others. We are doing this whole thing backwards.”
Pope Urban gave the Crusaders the guarantee of absolution for crimes committed. The Crusader started as “God wills it!” but that ultimately changed to
“Kill a Jew and save your soul.”
After they captured Jerusalem (July 15, 1099) Jews were herded into their synagogues, exits blocked and surrounded by soldiers, set on fire as the Crusaders sang, “Onward Christian Soldiers” or “Fairest Lord Jesus” as they burned the buildings to the ground.
The Jews were given an option:
Baptism or death!
The last major crusade was in 1271-1272.
Renounce the lie
The Jews are “more than bestial. They are an evil seed, a race who have not God for their father, but are of the devil.” (Bernard of Clairvaux who formed the second crusade)
Replace with the truth
And the Lord said to Moses, “When you go back to Egypt, see that you do all those wonders before Pharaoh which I have put in your hand. But I will harden his heart, so that he will not let the people go. Then you shall say to Pharaoh, ‘Thus says the Lord: “Israel is My son, My firstborn.’” (NKJV)
